ELECTRIGALLY HEATED ATOMIZER Filed Oct. 5, 1928 INVENTOR JOSEPH ROBINSON v ATTORNEYS Patented Jan. 16, 1934 UNITED STATES PATENT OFFICE My invention relates manna operated devices for app ying a medicament to the nasai'passages,

orgthroat, in vaporous or spray form, in the treatment of colds, and head and throat aiilictions. 6 In carrying out my invention I provide a suitable spray device and mount thereon electric means for heating the medicament to be used. The invention consists of the combination, ar-

' rangements, and constructions hereinatter'de- 10 scribed, pointed out in the appended claimspand illustrated in the accompanying drawing in which which Figure 1 is a sectional side elevation of my:

invention, and

Figure 2 is a plan view thereof.

In the drawing like numerals indicate similar Parts in the diflerent views. A suitable container 3, preferably madeoi glass, is provided with a sleeve 4, of suitable material, secured liquid tight to the top of the container. Into this sleeve is preferably threaded, liquid tight, a cap 5 carrying at one side one ormore horizontally disposed hollow tubes 6 and 6a and at the opposite side, and suitably connectedthereto, a rubber bulb 7. Attheir exireme ends the tubes 6a carry a nasal piece 8, which is perforated to permit exit of the sprays in using my invention. Between the nasal piece and the container 3 I mount my heating device. This consists of a housing 9., preferably of metal but which may be made of glass or other suitable material, with which thetubes 6 and 6a have slip fit air tight connection in the bearings 10. A cap 11 is thread ingly connected to the top of the housing in an air tight manner, the surface 12 assuring against leakage of air. A gasket maybe here provided ifdesired. The cap permits access to the lionsing for purposesof cleaning the housing, etc. Into the botiom of the housing I mount, also in an air tight manner, a heating element which consists of a member 14, of proper material, within which is positioned a. properly insulatedsuitable resistance coil 15. The coil is connected to an ordinary electric cord 16 inany proper way.

'I'henut or base 17 rigidly receives the member 14 and is preferably made of bakelite. The

. memberle lies in the path of travel of the sprays throughthe tubes 6 and 6a and is, for convenience, sometimes referred to herein, and in some ot the claims oithis application, as a heating element.

In operation, the medicament contained in they container 3 is, upon compression of the bulb "I, lifted to. the tubes 6 in any suitable manner, and driven therethrough in, the form of a spray.

In passing through the housing 9 the spray first strikes the heating element 14, which has been heated by admitting current thereto, thence on through the housing and out or the-nasal piece 8..

so "The sprays, being heated by contact with the heating element, are delivered to the aiiiict'ed parts while hot, thus greatly increasing their medicinal effectiveness. I I

I am aware that gariations and substitutions in and for the construction shown in the drawing may be made, and I do not 'therefore desire to be limited to the exact arrangement shown. I believe I- am the first to produce a. hand operated device for delivering direct to the nasal passages, or the throat,a medicamentin a vaporous 'or spray form which, with the air carrying it, is heated in the course the. instrument.

What I claim is:

1. A device of the character described, comprising in combination, a container adapted to contain a medicament, means for delivering said medicament in the form of a spray, said means comprising an air bulb and a tube connected with said coniainer on opposite sides of the vertical of its travel through axis of the container, and a housing into which v said tube extends, said hpusing containing an electric heating element disposed centrally thereof in spaced relation 'to the walls of the housing and against which said spray strikes, and is heated. v

2; A device of the character described, comprising in combination, a container adapted to contain a medicament to be atomized, means for atomizing said medicament; a conducting tube communicating with the said container, a nasal piece at the extremity of the said conducting tube, a chamber intermediate the lengths of he conducting tube, and means in the chamber for heating the said atomized medicament in its passage through the said tube, said heating means being arranged in the conducting tube in the path of travel of the atomized medicament so as to be enveloped by said medicament whereby the latter is heated by contact with the heating means;

* '3. Adevice of the class described, comprising,

in combination, a container adapted to contain f a medicament to be atomized, means for atomizing said medicament aconducting tube com municating with the said container, a nasal piece at the extremity of the said conducting tube, and

means interposed in said conducting tube for, heating the'atomized medicament in its passage through said tube, said means including aremovable housing havingja slip fit on spaced adjacent ends of said conducting tube and constituting a heating chamber, and a heating element projecting into said chamber in the path of said atomized medicament.
